Below the hood, the pipeline is powered by ComfyUI. Over the previous few months, NVIDIA has labored intently with ComfyUI to optimize efficiency by 40% on NVIDIA GPUs, and the most recent replace provides help for the NVFP4 and NVFP8 knowledge codecs. All mixed, efficiency is 3x sooner and VRAM is decreased by 60% with RTX 50 Collection’ NVFP4 format, and efficiency is 2x sooner and VRAM is decreased by 40% with NVFP8.
NVFP4 and NVFP8 checkpoints are actually obtainable for a number of the prime fashions straight in ComfyUI. These fashions embrace LTX-2 from Lightricks, FLUX.1 and FLUX.2 from Black Forest Labs, and Qwen-Picture and Z-Picture from Alibaba. Obtain them straight in ComfyUI, with further mannequin help coming quickly.
As soon as a video clip is generated, movies are upscaled to 4K in simply seconds utilizing the brand new RTX Video node in ComfyUI. This upscaler works in actual time, sharpens edges and cleans up compression artifacts for a transparent last picture. RTX Video might be obtainable in ComfyUI subsequent month.
To assist customers push past the bounds of GPU reminiscence, NVIDIA has collaborated with ComfyUI to enhance its reminiscence offload characteristic, often known as weight streaming. With weight streaming enabled, ComfyUI can use system RAM when it runs out of VRAM, enabling bigger fashions and extra advanced multistage node graphs on mid-range RTX GPUs.
The video technology workflow might be obtainable for obtain subsequent month, with the newly launched open weights of the LTX-2 Video Mannequin and ComfyUI RTX updates obtainable now.
A New Method to Search PC Recordsdata and Movies
File looking on PCs has been the identical for many years. It nonetheless largely depends on file names and spotty metadata, which makes monitoring down that one doc from final 12 months method tougher than it needs to be.
Hyperlink — Nexa.ai’s native search agent — turns RTX PCs right into a searchable information base that may reply questions in pure language with inline citations. It may scan and index paperwork, slides, PDFs and pictures, so searches might be pushed by concepts and content material as an alternative of file title guesswork. All knowledge is processed regionally and stays on the consumer’s PC for privateness and safety. Plus, it’s RTX-accelerated, taking 30 seconds per gigabyte to index textual content and picture recordsdata and three seconds for a response on a RTX 5090 GPU, in contrast with an hour per gigabyte to index recordsdata and 90 seconds for a response on CPUs.
At CES, Nexa.ai is unveiling a brand new beta model of Hyperlink that provides help for video content material, enabling customers to look by means of their movies for objects, actions and speech. That is best for customers starting from video artists searching for B-roll to players who need to discover that point they received a battle royale match to share with their associates.
For these fascinated about attempting the Hyperlink personal beta, join entry on this webpage. Entry will roll out beginning this month.
